SCWCD Exam Study Kit OR HFSJ?

I know HFSJ would be good but what other book should i get from amazon to help with the certification proceses? SCWCD Exam Study Kit? They say the second edition is not as good? Any other recomendations please?

Along with HFSJ I recently bought SCWCD study guide by David Bridgewater.It is like the K & B book we used for scjp and comes with a cd,two minute drill,exam watch etc.I have just started reading the book.
